Most common is a faulty crank sensor for this issue . Is the engine light on ? Was the crank sensor checked ?
Customer: replied 2 years ago.
no the engine light was not on and the engine seems to be idling low
Expert:  Cardoctor74 replied 2 years ago.
Ok then you need to have the crank sensor checked next . Was there any recent work done?
Customer: replied 2 years ago.
yes a clutch was fitted and i am waiting for a engine coolant sensor as that light is on
Expert:  Cardoctor74 replied 2 years ago.
Ok so the engine light is on then ? Did this all start happening after replacing the clutch?
Customer: replied 2 years ago.
no engine coolant light was on before the clutch was replaced the engine coolant is ok plenty of water in it
Expert:  Cardoctor74 replied 2 years ago.
No did the starting issue start after the clutch replacement ?
Customer: replied 2 years ago.
no did it once before clutch was replaced and idle seems to be low aout 600 revs
Expert:  Cardoctor74 replied 2 years ago.
Ok sounds like the crank sensor is starting to fail. What happens it heats up and then it will affect spark and idle and eventually stall the car . Also a faulty coolant temperature sensor can cause this also . This is what needs to be checked next . Also have a fuel pressure test to rule out a weak fuel pump. These are the next steps. Hoped this helped. Positive feedback and bonuses greatly appreciated.
